I think you've missed the point.

You *are* afraid to switch the master nameserver off because you *don't*
trust the slave and the whole point of the exercise is to find out if the
slave really is working or not.

Switching off the master in order to see if the slave is working is dumb
because if it turns out that the slave isn't working then you have no DNS.

Obviously if everything is working then you should be able to switch the
master off, but the purpose of this exercise is to safely determine that
everything's working in the first place.

You're approach is like suggesting that you wipe your disk and try to
restore from your backup in order to prove that your backups are working
properly.
